The star then evolved until it reached the red giant branch on the HR diagram, or until it reached an age of 10 billion years, the lifetime of the Milky Way. They calculated stellar populations ...

Let's say we want to build a model of the sun and Earth alone. Earth has a radius of about 6,371 kilometers (3,959 miles), but let's represent this with a marble 1 centimeter in diameter.

In fact, stars fell into several groups, and over the years we've learned about why that happens. Most stars are stable, like the Sun, and fall into the Main Sequence of the plot. Some are old, some ...
